For Release: April 29, 2004

The Bureau of Reclamation's Yakima Field Office announced today that flows from Bumping Lake Reservoir into the Bumping River will begin increasing around May 1. Current flows from the dam are about 150 cubic-feet-per-second. As of April 29, the storage level at the reservoir was about 4,000 acre-feet below the active capacity storage level of 33,700 acre-feet.

Between May 4 and May 7, Bumping Lake Reservoir is expected to approach the active capacity storage level and then flows into the lake will pass unregulated over the spillway and through the regulating gates. The current inflow rate of spring runoff into the reservoir is approximately 600 cubic feet per second. Once the reservoir is full, flows into Bumping River may range between 200 and 1000 cubic feet per second (or higher) during the spring runoff period.

Bumping Lake Dam and Reservoir is part of Reclamations Yakima Project and is located about 29 miles northwest of Naches, Washington. The 61-foot high structure was built in 1910.
